You need to multiply by 10 2 times.
So we know the lines are parallel.
Thus, the equation should look something like this:
y = 5x + b
Now, we have to solve for b.
Plug x=1 and y=2 into the equation to solve for b
2 = 5 + b
Subtract both sides by 5
-3 = b
b = -3
Plug that value into the equation.
y = 5x - 3
That's your answer.
Have an awesome day! :)
Answer:
Account 1 yields greater return.
Step-by-step explanation:
Lets solve for the first formula:
First, change 6.5% into a decimal:
6.5% -> 
-> 0.065
Now, plug in the values for Account 1:
<u>Now solve for Account 2:</u>
Change 6% into a decimal:
6% -> 
-> 0.06
Now plug in the values:
Account 1 yields better money after 10 years.
Answer:176 psychology textbooks and 98 Biology textbooks were sold.
Step-by-step explanation:
Let x represent the number of psychology textbooks that were sold.
Let y represent the number of biology textbooks that were sold.
textbook store sold a combined total of 274 psychology and biology textbooks in a week. This means that
x + y = 274 - - - - - - - - - - -1
The number of psychology textbooks sold was 78 more than the number of biology textbooks sold. This means that
x = y + 78
Substituting x = y + 78 into equation 1, it becomes
y + 78 + y = 274
2y = 274 - 78
2y = 196
y = 98
x = y + 78 = 98 + 78
x = 176
